摘要

摘要：铃木果蝇是一种臭名昭著的害虫，会对软皮水果造成严重危害。然而，目前对这一主要害虫的管理主要依赖于化学杀虫剂，这严重导致害虫产生抗药性并对环境造成危害。在本研究中，我们报告了艾蒿（艾草）精油在阻止铃木虫产卵方面的潜力。首先，我们发现艾蒿精油中的桉叶油醇能有效诱导铃木害虫避免产卵。其次，对桉叶油的产卵回避是通过激活成虫的嗅觉神经元介导的。此外，我们还发现桉叶油醇有可能抑制蝇类后代的发育，并通过肠道发育不良损害蝇类的存活率和寿命。最后，田间试验结果表明，艾草精油对葡萄园苍蝇具有威慑作用。总之，我们的研究结果表明，桉叶油醇可作为一种生物防治剂，通过阻止产卵来防治铃核蝇，突出了针对铃核蝇的害虫综合防治计划的基本概念。

Mugwort essential oil and its major constituent, eucalyptol, elicits oviposition avoidance of Drosophila suzukii

Abstract: Drosophila suzukii is notoriously a pest that causes serious damage to soft-skinned fruits. However, the management of this key pest currently relies on chemical insecticides that seriously cause pest resistance and environmental hazards. In the present study we reported the potential of Artemisia argyi (mugwort) essential oil to act as deterrent for D. suzukii oviposition. First, we identified that eucalyptol of mugwort essential oil efficiently induced the oviposition avoidance of D. suzukii. Second, the ovipositional aversion to eucalyptol was mediated by the activation of olfactory neurons in adult. Moreover, we found that eucalyptol potentially arrested the development of the fly progeny and impaired the survival and lifespan of flies through intestinal dysplasia. Finally, the result of field trials showed that mugwort essential oil had a deterrent effect on vineyard flies. Overall, our findings show that eucalyptol potentially acted as a biological control agent against D. suzukii by deterring oviposition, highlighting fundamental concepts of integrated pest management programs against D. suzukii.

期刊介绍： Its scope covers all aspects of basic and applied research dealing with insects and more broadly with arthropods inhabiting wild, agricultural and/or urban habitats. The journal also considers research integrating various disciplines and issues within the broad field of entomology and ecology. Entomologia Generalis publishes high quality research articles on advances in knowledge on the ecology and biology of arthropods, as well as on their importance for key ecosystems services, e.g. as biological control and pollination. The journal devotes special attention to contributions providing significant advances (i) on the fundamental knowledge and on sustainable control strategies of arthropod pests (including of stored products) and vectors of diseases, (ii) on the biology and ecology of beneficial arthropods, (iii) on the spread and impact of invasive pests, and (iv) on potential side effects of pest management methods. Entomologia Generalis welcomes review articles on significant developments in the field of entomology. These are usually invited by the editorial board, but proposals may be sent to the Editor-in-Chief for preliminary assessment by the editorial board before formal submission to the journal. The journal also considers comments on papers published in Entomologia Generalis, as well as short notes on topics that are of broader interest.
